Description
Technical field
The invention belongs to aviation field, relate to the undercarriage of aircraft, especially a kind of multifunction aircraft undercarriage dismounting vehicle.
Background technology
The overhaul quality of aircraft with stop field time, be directly connected to the economic benefit of aircraft reliability of operation and airline and the prestige and the economic benefit of maintenance company self.Undercarriage is one of four big critical components of aircraft, also is the important load parts of aircraft, in the process of takeoff and landing, is undertaking the safe key player that rises and falls.It is that aircraft stops heavily one of important content in the maintenance work of field that undercarriage is changed, and what the replacing efficient of undercarriage directly had influence on aircraft stops field time and repair quality.Dismounting to undercarriage in aircraft maintenance has not belt wheel dismounting and two kinds of assembly and disassembly methods of belt wheel dismounting.Not belt wheel dismounting of what is called, referring to undercarriage wheel in disassembly process need remove from wheel carrier.This assembly and disassembly methods decomposes wheel and wheel carrier, and the dismounting of wheel is simple relatively, and mainly dismounting is the wheel carrier part of undercarriage, and the weight and volume of wheel carrier all reduces greatly, and dismounting is also simple relatively.The belt wheel dismounting; Be that undercarriage is in the process of dismounting; Wheel needn't be removed from wheel carrier; This assembly and disassembly methods is regarded as one with wheel and wheel carrier, and the dismounting difficulty is relatively large, as long as but be applicable to that the routine maintenance that can accomplish undercarriage can not need remove the general aircraft maintenance inspection of wheel and be the situation of installation wheel earlier of saving time from undercarriage.Specifically select for use which kind of assembly and disassembly methods to be determined on a case-by-case basis.Observe discovery through keep in repair a line in enterprise, because main landing gear does not have special dismounting vehicle, so disassembly process is not only time-consuming but also require great effort, working strength of workers is very big.In the whole overhaul process of aircraft; Different time section workload is differentiated; Can assemble undercarriage in workload, then directly belt wheel is installed and is got final product more after a little while, workload that so not only can balanced different time sections but also can save time; So for reducing the aircraft overhaul time, main landing gear adopts the method for belt wheel dismounting.
Through many airdreadnoughts of tracking investigation---the B747 aircraft is installed the process of undercarriage and found: the fuselage mounted landing gear of this aircraft is installed and is adopted the not mode of belt wheel installation, and undercarriage is placed on the undercarriage transport vehicle and installs.The undercarriage transport vehicle is simple in structure, does not have regulatory function, has only preceding two wheels can play the effect that turns to, and can only realize the function that undercarriage is transported.Up-down adjustment when undercarriage is installed leans on the shock strut of undercarriage self to realize, the adjusting of rotation all around realizes by manpower.The wing undercarriage is installed the mode that adopts belt wheel to install, and regulates more laborsaving like this with putting the transparent plastic cloth of putting the oil under the wheel during installation.The adjusting of all around rotating when undercarriage is installed realizes that by manpower up-down adjustment realizes by the hydraulic system that is installed on the undercarriage cushioning pillar.But this method mainly leans on manpower to accomplish, and automaticity is low, and labour intensity is big, inefficiency, and also the personnel of needing repairing have rich experience simultaneously.
Through retrieval, do not find that as yet effective technical means solves the dismounting problem of airdreadnought undercarriage.
Summary of the invention
